If you press the Bixby button on Galaxy S9 or S9+, the phone will open Bixby Home.

If you long press (press and hold) the Bixby button, the phone will open Bixby Voice.

Samsung does not allow you to map the Bixby button on Galaxy S9 and S9+ to any other apps. It can only be used for Samsung Bixby unless you root the phone and mess up a few system settings.

Although Samsung Bixby has been dramatically improved since the initial release with Galaxy S8, in many aspects, it is still not comparable to Google Assistant, which can be enabled in Galaxy S9 or S9 by long tapping (tap and hold) the Home button. Some Galaxy S9 and S9+ owners may not want to use Samsung’s Bixby at all. They are happy with Google Assistant.

Some other owners may do not use either Google Assistant or Bixby. But they may press the Bixby button accidentally when they want to press the volume button or the power button.

Even for some Bixby users, they may not want to use the Bixby Home, which comes out when you press the Bixby button. You can use other Bixby features without the button.

So, there are sizeable Galaxy S9 and S9+ owners may want to disable Bixby button in Galaxy S9 and S9+. A few may even want to disable or uninstall Bixby from Galaxy S9 or S9+.

As Bixby is deeply integrated into Galaxy S9 and S9+, it is hard to uninstall or disable Bixby entirely without breaking some core features and functions of the phone.

But it is easy to disable Bixby button in Galaxy S9 and S9+.

Please note, Samsung does not allow you to map the Bixby button in Galaxy S9 or S9+ to other apps or functions. Samsung simply blocked this feature.

So, you have the two options for the Galaxy S9 Bixby button: use it or disable it.
